Hi alpinists,   I am trying to work out the best way to belay in an alpine situation.   I have heard of and read about the 'dynamic belay'. I am wondering has anyone actually done this in a real climbing situation?   The 'dynamic belay' is when you let the rope run through your hands when the climber falls before locking it off. I am not after people who have only practiced it - that is knowing that the climber is going to fall.     Thanks,   Marty
